rAsTENING BUTTON.

Application filed August 26, 1926, Serial No. 131,776, and in France July 15, 1926.

My invention relates to a fastening button which is chiefly adapted for use upon Aautomobile carriage bodies for securing curtains, canvas or leather covers and the like, and which comprises disappearing roller-s or balls.

My said device offers the perpendicular feature consisting 'in the fact that it is buttoned by a simple pressure upon the female part or eyelet of the canvas cover or curtain, or like member, and cannot be disengaged by any eftort of traction upon the latter', however great this efort may be.

Thel following description, with reference to theV appended drawings which are given by way of example, discloses various embodiments of the invention.

Fig. 1 is a section of a form of construction .of the said but-ton device, and,

Fig. 2 is a section on the` line le-X of Fig. Vl.

Fig. 3 tion, and,

Fig. 4; is a section on the line Y-Y of Fig. 3. 1

Fig. 5 isa partial. section of another modii'ication7 and Fig. 6 is the'corresponding plan View.

Fig. 7 is a partial section of another form of construction, and,

Fig. S is the corresponding plan view.

As observed in Fig. 1, my said button device comprises a male part which is provided with a central axle. a having a rcstricted portion Z); said axle is supported at the bottom by the disc c which lis mounted in the cylindrical envelope (Z, this being secured in any suitable manner to the canopy or canvas cover 7L', for instance by means of the eyelet e, a disc e1 being disposed upon the other face of the canvas f.

A t its upper part, the cylindrical envelope [Z forms the second support for the axle a. llTithin the said envelope are mounted the rollers or balls g, which are for instance three in number and are slidable in the slots g1 formed in the envelope 0Z. 1

The rollers or balls g are mounted in a cage having the form of a pressure button and consisting essentially of two concentric sleeves ZL and c' which are secured together. The externalv sleeve h is slidable upon the envelope Z and is provided with apertures through which each of the said rollers or balls may partially extend. The internal Sleeve v? extends wit-hin the envelope d and,

is a vertical section of a modificay is provided with aperturesthrough which the said rollers or balls may extend. bottom ofthe sleeve z' is closed bythe disc j; a spring 7c abuts at one end against the disc c and atthe other end against the disc The l j, and it urges upwardly the said pressure button (i. e. the cage ZL-z') which dravs with it the rollers or balls g.

The female part of the button device consists of-an eyeletZ which is suitably secured,

for instance by means of the disc Z2, to the canvasl member (or the like) fm which is to be fastened to the member f. The operation of my said button device is follows:

lVhen theA cyelet Z is engaged upon the male partA of the button, the lower' edge Z1 of the said eyelet, whose diameter is less than the diameter of thecircle passing through the extreme router points ofthe rollers or balls ,f/,draws with it the said rollers, which thus descend along the axle a and attain the position which is shown in the dot and dash lines lin Fig. 1. In this position,the` said rollersmay engage the restricted part Z) of the kaxle a, so that they will .disappear within the cage ZL; The eyelet may then descend beyond the said rollers, and as soon as this occurs. the cage L-z' togetherwith the rollers will be raised by the spring Zt", and the axle will again pass between the said rollers or balls, thus spreading them out into the position shown in Fig. 1, and thereby preventing the said eyelet from leaving the .male portion, so that the parts of the button device will be properly secured together. It will be observed that ink this position, it will be impossible to remove the .femaler trom the male part by drawing upon the canvas m. To detach the female part, I press withv the thumb upon the cage ZL-z', and at the same time use the other fingers of the hand to draw upon the canvas m. By pushing with the thumb upon part L-Q, I lower the said rollers or balls g, and these will assume the position shown in the dot and dash lines in Fig. 1, thus disappearing and allowing the eyelet Z to be detached.

To obviate any play between the male and female parts in the assembled position shown in Fig. 1, I may dispose upon the external sleeve Z2, a flanged ring a which is shown in the dot and dash lines in Fig. 1, and the lower edge Z1 of the eyelet Z will be held between the rollers or balls and the ring a.

In Fig. 2l, which shows a modied construction employing suitable balls, the male part-s of the button` instead of being` secured by the eyelet n is secured by a screw shank 79. Thisl device is particularly adapted for use in the case .in whi'cliythe male part is to 'be mounted upon a panel of wood or other material, into which the shank y) can be screwed. ltis to be noted that the axle ci is held only at its lower part, and is yriveted to the dise c. The push-piece or cage containing;v the balls g comprises but a single sleeve i, which is slidable in the cylindrical outer envelope d.

In the modification shown in Fig'. 5, the male part is mounted on an oval base q which is apertured at q1 q for the insertion of Wood screws.

ln the modified construction shown in Fig. the male part is secured to a claw base r Whose claws 81 are inserted through the canvas or -like member j and through slots formed in the oppositel'v-disposed dise .9, the said claws being bent down as shown in Fig. 7.

My said button device is applicable for the fastening of all curtains, canopies or like members employed for closing purposes, whether of canvas, leather, Wood, metal or the like, upon correspondingparts consisting` vof canvas, leather, Wood, metal or other material.. The eyelet or female part, with its facing plate, are not absolutely essential, provided the part upon which the device is applied is ot' sutiicient strength, this con'- sist-,ing for insta-nce of Wood, metal, celluloid or the like.

Obviously, the said device is susceptible of all suitable moditications in detail, Without departing;` from the spirit of the invention.

'lVhat I claim l. A button device coml'n'ising;l a-'male part consisting` of a slotted casing, an axle disposed in the interior ot' the said male part, a portion of the said axle having a reduced diameter, fastening elements extending through the slots in the said casing and slidable along' the said axle, a cylindrical sleeve adapted to slide in the said casing and to draw with it the said fasteningI elements which will disappear when they coincide with the restricted part of the said axle, a spring upwardly urging the said cylindrical sleeve and adapted to maintain the said fastening` elements in the 'fastening position, an eyelet enactingv with the casing of 'the male part.

2. A, button device comprising a male vpart consisting` of a slotted casing, a stationary axle secured in the interiorl of the said easing, said axle having a restricted portion, fastening elements extending through the slots in the saidcasing and slidable along the axle, means for 'displacing said fastening elements in the slots of the casing and along the axle whereby the said elements disappearl when'they coincide with thev restricted part of the axle, elastic means for returning to normal position the means serving to displace the fastening elements` and an eyelet coacting With the male part.

l'n testimony whereof I have signed this specification. A t
